Description

Thompson Peak was constructed and opened in June 1931. The lookout is an R1 design, a Region 1 revision of the California Region 4AR per Thornton. The tower is enclosed timber at 9 feet tall.

Thompson Peak also hosted the Janesville Gap Filler Radar Annex facility from 1958 to 1970.

The Site was utilized by the US Air Force as an Aircraft Control & Warning (AC&W) site. This AC&W Site was part of the Semi-Automatic Ground Environment (SAGE) radar system. The Former Janesville GFA utilized an AN/FPS-18 model gap filler radar, where "AN/FPS" is an acronym for Army-Navy Fixed, Pulsed radar, Search electronic device. (www.militarymuseum.org)
